The present work experimentally investigate self-compacting concrete (SCC) of M35 grade for workability and compressive strength by using two different brand of cement. The type-I and type-II brand of cement are Birla OPC-53 and Ultra Tech OPC-53. SCC is runny fluid mix it does not require any external vibration while placing in the formwork. The fluidity of SCC is achieved by using fine aggregate, cementitious material, chemical admixture and super-plasticizer. Due to high volume of cement and chemical admixture used in it increases the cost of SCC. To overcome this problem, ground granulated blast furnace slag (GGBS) can be used as an alternative to cement, which acquires the same cementitious properties as that of cement. The effective utilization of GGBS in SCC is indirectly aiding waste reduction, reduction in carbon foot print and maintaining ecological balance in the environmental system. In the present study, the fresh properties of SCC are measured as flow value, L-box and plastic density. The compressive strength is measured at 3, 7, 14 and 28 days in moist curing for water-to-cement ratio 0.34 in harden state. Substitution level of GGBS in the concrete is kept at 35%. It is noted that the compressive strength of type-I cement is more than type-II cement.

摘要

The present work experimentally investigate self-compacting concrete (SCC) of M35 grade for workability and compressive strength by using two different brand of cement. The type-I and type-II brand of cement are Birla OPC-53 and Ultra Tech OPC-53. SCC is runny fluid mix it does not require any external vibration while placing in the formwork. The fluidity of SCC is achieved by using fine aggregate, cementitious material, chemical admixture and super-plasticizer. Due to high volume of cement and chemical admixture used in it increases the cost of SCC. To overcome this problem, ground granulated blast furnace slag (GGBS) can be used as an alternative to cement, which acquires the same cementitious properties as that of cement. The effective utilization of GGBS in SCC is indirectly aiding waste reduction, reduction in carbon foot print and maintaining ecological balance in the environmental system. In the present study, the fresh properties of SCC are measured as flow value, L-box and plastic density. The compressive strength is measured at 3, 7, 14 and 28 days in moist curing for water-to-cement ratio 0.34 in harden state. Substitution level of GGBS in the concrete is kept at 35%. It is noted that the compressive strength of type-I cement is more than type-II cement.
